Title: Adsorbent
Inventor: NAGATA YASUTOSHI
IPC: B01J20/04
Filed: 1987-09-09
Abstract: PURPOSE:To inexpensively produce an adsorbent capable of adsorbing basic and acidic substances, difficult to dissolve, and having excellent heat resistant by introducing bivalent metal ions into phosphate rock and/or coral lime by ion exchange. CONSTITUTION:Phosphate rock or coral lime is pulverized, added to the soln. of the salt of the bivalent heavy metal ion to be introduced kept at about 4-6pH, and agitated to obtain ion-exchange particles. These particles are separated, and dried to be used as adsorbent. Since the obtained adsorbent has a high initial adsorption rate as compared with activated carbon, is capable of adsorbing even acidic substances, unlike the chemical adsorbent which adsorbs only basic substances, and is stable even at the high temp. of 500 deg.C, the adsorbent can be worked into an applied product.

Title: Film type camera
Inventor: MURAKAMI SUSUMU
IPC: G03B17/24
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To substantially enlarge the effective photographing area and to improve image quality by eliminating perforations from a film whose width is 35 mm and enlarging the length of a frame in the film width direction. SOLUTION: An effective photographing area is enlarged by eliminating through-holes for driving a sprocket (perforations) for a film 1. Then, the film 1 is wound up between a cartridge housing part and a film housing part. Further, small holes 6 are formed on a line being 1.25 mm from one edge part of the film 1, that is, on a center line between the edge part and the frame 3 at a pitch (A) of 5.25 mm or a pitch (B) of 6.28 mm. Then, the number of the holes 6 is counted by using infrared rays at the feeding time of the film 1. When the counted number becomes a prescribed number and the feeding of the film 1 is stopped, the frames 3 are formed on the film 1 at the correct pitch. A magnetic mark or the like can be substituted for the small holes 2 in order to detect the feeding amount of the film 1.

As a result, a window region of about 60meV is formed for the generated wavelength in the direction of oscillation axis, and refractive index difference of 1X10<-2> is formed in the lateral direction as compared with the active region so that remarkable improvement in characteristics can be achieved.
